Nematus brevicornis Thomson, 1863: 622-623. Primary homonym of Nematus brevicornis Förster, 1854b [= Euura brevicornis ( Förster, 1854b)]. Syntype ♀ (MZLU2014457) in MZLU, examined. Type locality: Småland and Skåne, Sweden.

Nematus maestus Zaddach, 1876: 85-86. Syntypes ♀ and ♂ possibly destroyed ( Blank and Taeger 1998). Type locality: Danzig, Poland.

Nematus parvicornis W.F. Kirby, 1882: 118. Replacement name for Nematus brevicornis Thomson, 1863.

Pachynematus insularis Malaise, 1921: 7-8. Syntype(s) ♀ in MZLU, not examined. Type locality: Resarö Island, Sweden. Synonymised with P. brevicornis by Lindqvist (1955a).

Similar species.

Females are perhaps most similar to P. biscalis , from which P. maesta differs by having pale cercus (black in P. biscalis ) and black clypeus (at least partly pale in P. biscalis ). Males are best recognised by examining penis valves.

Genetic data.

Based on COI barcode sequences, P. maesta forms its own cluster (no BIN number has been assigned yet) (Fig. 5). The nearest neighbour to P. maesta , diverging by a minimum of 5.95%, is BOLD:AAF5120 ( P. nigella and P. amphibola ). Based on nuclear data (one specimen and NaK), the nearest neighbour is 0.7% different ( P. geniculata ).

Host plants.

Malus sylvestris (L.) Mill. and M. domestica Borkh. ( Pschorn-Walcher and Altenhofer 2000).

Distribution and material examined.

West Palaearctic. Specimens studied are from Finland, France, Germany, and Sweden.
